Abstract

In this paper, the TOU tariff's based building indoor temperature control algorithm in cooling systems is proposed using control horizon method. A control horizon switching method and linear programming algorithm is used for optimal control, and both TOU and peak tariffs are included to calculate the energy costs. Simulation results show that the reductions of energy cost and peak power can be obtained using proposed algorithms.

본 논문에서는 TOU 요금제 기반에서 제어구간 설정방법을 사용한 건물 냉방시스템 실내온도 제어 알고리즘을 제안한다. 건물 실내온도를 최적제어하기 위한 제어구간 설정은 스위칭방법과 선형계획법을 사용하고 냉방시스템 사용요금은 TOU와 피크 요금을 포함하여 산정한다. 시뮬레이션을 통해 제안한 제어구간 설정방법을 적용하면 전력 사용에 따른 비용의 절감과 피크 전력 절감을 확인할 수 있다.
